URSANE AND OLENANE TRITERPENES FROM ASTRAGALUS PROPINQUUS

Venkata Sai Prakash Chaturvedula and Indra Prakash

Continuation on the phytochemical studies of the dichloromethane (CH2Cl2) fraction of the aqueous extract of Astragalus propinquus furnished two triterpenes namely α-amyrin and β-amyrin. The structures of the two isolated compounds were characterized on the basis of extensive spectral studies and literature search. The complete 1H and 13C NMR spectral assignments of the two isolated compounds are reported on the basis of 1D (1H and 13C) and 2D (COSY, HSQC, and HMBC) NMR spectral data.
